Designs and variants

SKF support rollers are available without (fig. 1) or with (fig. 2) flange rings. They have a thick-walled outer ring with its running surface crowned as standard. However, support rollers with a cylindrical (flat) running surface are also available (designation suffix X).

Support rollers without flange rings require adjacent components to guide the outer ring and cage axially.

Support rollers with flange rings do not need adjacent components to guide the outer ring and cage axially (fig. 3). Axial loads, which are induced when shafts are not horizontal or aligned properly, are accommodated by the flange rings.
